| Abstract: | The queueing systems with nonexponential service d istributions have been widely applied in many areas, such as communication networks and managemen t systems. In this paper, by using the approach of performance potential, the pr oblems of sensitivity estimates and simulation of the steady state perf o rmance for M/PH/1 queueing systems are studied. An algorithm to compute potentia ls and perfo rmance derivatives is proposed. This algorithm can be directly used in controlli ng and optimization problems as it is based on analyzing a single sample pa th of a queueing system. A numerical example is provided to illustrate the applica tion of the algorithm. |
